Abstract : The generalized likelihood ratios needed for detection and other types of hypothesis tests in decision-theoretic antenna processing systems are presented for the case of time-varying but statistically stationary returns with N antenna elements, K targets, K discrete clutter sources, and uniform background clutter and receiver noise. Likelihood ratio tests for the detection of one or more targets versus no targets are given for scintillating target signals and scintillating clutter and for nonscintillating target signals and scintillating clutter. A block diagram of a detector for an antenna processor that can perform these tests is presented. The probability distributions that were developed are also given and are immediately applicable to estimation as well as to hypothesis testing. (Author)
